CASEMENT WINDOW.

Application filed March 29, 1928.

The object of the present invention is to provide a casement window soconstructed as to be both wind and water-tight, the elements of thewindow being so formed and related that they may be constructed ofeither wood or metal and assembled preliminary to placement in thewindow openings provided for that purpose in the buildings.

The invention will be described with reference to the accompanyingdrawings in which Figure 1 is an elevation of the embodiment of theinvention from within the building;

Figure 2 is a vertical section on the line 2-2, Fig. 1;

Figure 3 is a horizontal section on the line 3-3, Fig. 1, and

Figure 4 is an enlarged detailed sectional view showing the relationshipof the window and casement frame at the hinged portions thereof.

The casement comprises a main frame having a header 1, side framemembers 2, 2 and base frame member 3, which may be formed with an outersill projection 3". A lintel frame 4 may be carried by header 1 abovewhich may be secured the lintel 5 with a downwardly extending crosspiece 6. The outer wall of header 1 at its lower edge is formed with arabbet so as to provide a lower shoulder a and an upper shoulder Z) fora purpose hereinafter to be explained. Base frame member 3 is formed atits outer face at the upper portion thereof with a rabbet, thusproviding a shoulder 0 and a second shoulder (l.

The window of the easement comprises the vertical window members 7, 7the lower member 8 and the upper member 9. The lower member is doublerabbeted providing two horizontal shoulders corresponding with shoulders0 and (Z of base frame member 3. The upper window member 9 is formed inits top surface with a channel thus providing two shoulderscorresponding with the shoulders a and Z) of the frame header 1. Member7 is provided on its outer vertical edge with a channel to correspondwith a similar channel formed in vertical frame member 2 so that the twomembers have a shoulder abutment at e and a second shoulder abutment atf.

Vertical window member 7 X is formed with a longitudinally extendingchannel of the formation shown more particularly in Figs.

Serial No. 265,560.

3 and 1. This channel provides a shoulder g which abuts the outer faceof frame mem her 2*, the frame member being formed with a verticalgroove of such formation as to form a shoulder h which is abutted by theinner face of window member 7*. Thus the hinged portion of the window isprotected by double shoulder engagement between the casement frame andthe window frame. The hinges, of which one is shown in Fig. 3, may havetheir wings inserted in slots in the members 2", 7 If pin hinges areused, removal of the pins will not enable opening of the window whenwindow frame member 7 is latched on the inside to vertical frame member2 because of the interlocking of mem bers 2 7*, as will be seen frominspection of Fig. 3.

Frame members 2, 2 may be grooved to receive the tenons of the verticalfinishing pieces 10 and the latter may be connected at the top byhorizontal member 11 and at the bottom by base member 12. Base member 12may carry the inner sill 13.

At the inner wall of the building and adjacent to the easement opening,in abutment with finishing member 10, and resting upon inner sill 13 maybe placed the inner frame members 14, 14* at the top of which is thecross piece 15. These members may at their outer edges lie in abutmentwith the mouldings 16. Hinged to frame member 1 1 is a window or screenframe 17, each vertical. member of which may be formed with twoshoulders i, is, the latter lying in abutment with the finishing pieces10 and the shoulders 2' lying in abutment with inner frame members 14,lt respectively.

It will be seen by reference to Fig. 2 that the easement window at itstop is sealed against the admission of water by the double shouldercontact with header 1 and is shielded by the lintel frame. The base ofthe window is likewise sealed by double shoulder contact with outer sill3*. The vertical window frame member 7 is sealed by double shouldercontact with member 2 and the vertical window frame member 7 is sealedat its hinge connection with frame member 2 by the two shoulders g andh. Exterior of members 2 and 2 may be placed the lining members 18 whichmembers may be connected by tongue and rabbet with casement framemembers 2, 2".

The casement as a whole may be assembled prior to its insertion in theeasement opening of the building and its construction is par,- ticularlyadapted for Wooden easements. lVarping is prevented by the interlockingof members 7 52 and by the double shoulder engagement between the othercontacting elements of the Window and its surrounding frame members.

Having described my invention what I claim and desire to secure byLetters Patent is as follows 1-- In building construction and incombination. with a casement opening the Walls of which comprise anouter rectangular section and a comn'iunicating inner rectangularsection of lesser transverse area, atl'ording opposed vertical Shouldersintermediate said sections, of a casement window comprising arectangular outer casement frame having its vertical side members 2*abutting said shoulders a rectangular linerframe connected to theeasement frame, both window frame and the easement frame beingchannelled providing a plurality of shoulders abutting at the sides andat the top and bottom of said frames When in engagement, means forhinging one side of the Window frame to the easement frame, arectangular liner 10, 11, 12 projected inwardly of the outer casementframe and lining the casement opening of lesser transverse area, innerframe members 13, 14, 14 l5-and inner casement window frame 17 hingedthereto.

In testimony whereof, I have signed my name to this specification.
